Netizen question: Hello. I have always liked grapes. Recently, a friend told me that the nutrition of grape seeds and skins is better than that of pulp.

If you can stand the dry taste, it is better for your health to chew up the whole grape and swallow it together.

Excuse me, is this really the case?

In fact, grape skins and grape seeds do contain many healthy ingredients beneficial to human body, such as polyphenols and resveratrol, which have antioxidant and cardiovascular diseases.

However, these healthy ingredients have poor water solubility.

In other words, you want to get these healthy ingredients by chewing your teeth, stirring your tongue and extracting saliva. And the effect is not ideal.

In addition, grape skins and grape seeds contain a lot of tannins, which will not only produce strong astringency, but also cause damage to the digestive tract if eaten too much.

Therefore, it is strongly recommended that when you eat grapes, you should eat the seeds and skins together.

What should I do to get healthy ingredients from grape skins and seeds?

In fact, the solubility of healthy components such as polyphenols contained in grape skins and grape seeds in ethanol will be greatly improved.

Soaking grape skins and grape seeds with ethanol for many days can extract these healthy components quite fully.

Therefore, if you want to eat the "treasures" in grape skins and grape seeds, you can crush them, soak them in white wine for about two weeks (during which you can shake them frequently), filter out the dregs, make them into grape skins and grape seed wine, and mix them with grape juice for drinking.

Of course, after all, alcohol will have an impact on the body, so I suggest you drink alcohol in moderation. If it really doesn't work, eat grape meat, which is also very nutritious.
